The said shell 10 additionally provides means for supporting the inner cooking receptacle in an upright fixed position while eggs are beaten therein by the use of an egg beater. It will also be further noted that the rounded or semi-spherical bottom of the receptacle provides an excellent medium in which to mix any food ingredients with either an egg beater or mixing spoon as none of these ingredients can get into corners of the receptacle as in the usual mixing or cooking utensil.

In the form shown in Figure 6 the food cooking receptacle 22 is practically the same as the receptacle 14 except that its bottom 23 is fiat and slightly rounded as indicated by the numeral 24.

The modified supporting shell 21 may also be used to support the food cooking receptacle 14 and 22 on a stove or over a gas burner and to retain the heat under the receptacle, that is, when the inner receptacle is utilized for cooking purposes without the outer water containing receptacle 8.

What I claim and desire to secure by Letters Patent of the United States is the following:-

1. A double boiler comprising an outer vessel provided with a neck open at its upper end, a supporting shell concentric with said neck and open at its bottom, said shell having an open upper end provided with a shoulder adapted to rest upon the open end edge of said neck, and an inner receptacle having a hemispherical bottom and an enlarged upper portion providing an annular shoulder so positioned as to rest upon the shoulder of said shell.

2. A double boiler comprising an outer vessel provided with a neck open at its upper end, 2. Supporting shell concentric with said neck and open at its bottom, said shell having an open upper end provided with a shoulder adapted to rest upon the open end edge of said neck, said shell also having a series of openings of substantial size in its wall located in a plane adjacent to the lower end or the shell, and an inner receptacle having a hemispherical bottom and an enlarged upper portion providing an annular shoulder so positioned as to rest upon the shoulder of said shell.
